To allv whom, 'it .may con/cern: l

Be it known that LSIDNEY L. LONG, a citi- Zen of the United States,residing at Minneapolis, in the county of Hennepin and State of vendingmachines of that general class in.

which the weight of a'deposited coin serves Ism.

One objectof the invention is to providea i -machine which will insurethe delivery of the articles when a coin of proper value is inserted, 3so that therewill be no risk of the intending, purchaser losing money ifhe fails to prop-v erly operate or to depress the actuating-lever fullyat the first attempt.

A further object ofthe invention is to pro.- vide a machine of thischaracter in which after the operating movement of the lever Y has beenstarted it will be impossible to force it to return to initial positionuntil after it has completed. the full discharging movement, thuspreventing manipulation of the` machine and the delivery of more than asinf gle article in return for each coin inserted.

With these and other objects inv view, as will more fully hereinafterappear, the invention consists inthe novel construction and arrangement.of parts hereinafter fully described, illustrated in the accompanyingdrawings, and particularly pointed out in the appended claims, it beingunderstood that various changes in the form, proportion,si`ze, and minordetails of the structurernay be made without departing from the spiritVor sacrificing any of the advantagesv ofv the invention. 4 K v In theaccompanying drawings, Figure 1 is a sectional elevation of a coincontrolled vending-machine constructed in accordance` v devicesv inadvance of a complete depression of the operating-lever.y Fig. 4 is adetachable perspective view of the coin-receiving bucket and the catchconnected thereto.

Similar numerals of reference are employed to indicate correspondingparts throughout the several figures of the drawings. 4

' tained in a suitable casing 1, which may be Patented ivrach 27, 1906.

of ornamental character, and at the front of the casing is adelivery-table 2, on which the `goods, are discharged, the articlesbeing deyivered through a suitable 'openin that is shielded by a hood 3.The front o? t 'ing also carries a slotted plate 4 for the passage of anoperating-lever 5 and has a slotted he casescutcheon '6 in alinementwith the endl of the coin-chute. Within the casing is a magazine 7,adapted to contain the articles to be delivered, suchas smallpackages ofchewinggum or candy, the delivery being accomplished by a slide 8,adapted to suitable vguides 9, carried by the casing. To the inner wallofthe casing is secured la cast baseplate 10, havin a bearing for thereception of one end of a s aft 11, the Ashaft being provided with asupport in the form of a bracket projecting from the front Wall of thecasing. To the outer end of the shaft is secured a rocker-arm 13, thatextends u ward through ltheslot in the said slide and orms anactuatingmeans therefor.

To the inner end of the shaft 11 is rigidly secured a bell-crank lever14, having two i tegral with the base and serving as a stop for ilimiting movement of the lever. lTo the upper end of the lon er arm 15is pivoted a pawl 18, that is normal y held in a central position -or inthe general plane ofthe arm 15 bymeans of a coiled Atension spring -19that lis connected at its lower end to a lug 20, projecting from' thearm 15, the spring serving to permit swinging movement of the Ipawl inboth directions. The pawl is adapted to engage the teeth of a rack 21,carried by the baseplate 10 and arranged on a curved line struck fromthe aXis of the shaft 1 1, the pawl traveling freely over the teeth asthelever is moved in both directions, but when 'once in mesh with therack-teeth serving to fpositively pre'- vent any return movement a terthe movement in either direction has commenced and the return movementcannot be permitted under any circumstances until a full stroke of i thelever has been accomplished. -Y To the shorter arm of the bell-cranklever 14 is pivoted a bell-crank lever 25, the longer arm 26 of which isprovided at its outerend with a coin-receiving cup 27, disposed at theend of the coin-chute 28, -the bottom lof the coin-cu having a slot ofsuch size as to permit of t e passage of coins orvother articles ofsmaller diameter than that of the coin necessary to operate the machine.The longer arm of the lever is connected to the lug 20 by means of alight tension-spring 2S, and the shorter arm 29 of said bell-crank leveris in the form of a catch that is adapted to engage with the rear end ofthe operating-lever 5.

The operating-lever 5 is loosely mounted on the shaft 11, being heldinproper position on said shaft by an auxiliary sleeve or collar 32,

and the front end of the lever is normally held in elevated position bymeans of a strong tension-spring 33, extending between the lever and alug carried by the frame, the lug serving also as one of the supportsfor the frame. The rear end of the lever is pointed in order that it maybe properly engaged by the catch 29, and downward movement of the rearend of said lever is limited by a pin 37, carried by the arm 16 of thebell-crank lever 14, so that the stress of the spring 33 is thustransferred in part to the bell-crank lever 14, and the upper arm 15 ofthe latter is held against the stop-lug 17. When the parts are in normalposition, the lever may be depressed without effecting any movement ofthe ldischargeslide until after a coin has been inserted. On theinsertion of a coin, if of proper value, the coin will pass down throughthe chute vand will be caught in the cup of said lever, its vweightovercoming the stress of the light tension-spring 28 and causing thecatch 29 to engage the rear end of the operating-lever 5. When the leveris depressed, its rear end will carry the catch 29 with it, and thismovement will be transmitted to the bell-crank lever 14 and through thelever 14 to the shaft 11 and the delivery-slide, causing the dischargeof the lowermost article in the ma azine. The discharging movement ofthe ever causes the pawl 18 to engage with the teeth of the rack 21, andduring this movement the pawl is shifted to aposition at an angle to thegeneral plane of the arm 15, so that the radial distance between theaxis of the shafts 11 and the end of the pawl when the latter is engagedwith the rack will be less than the normal distance when the pawl isstraight, sothat when once the pawl is engaged with the rack it will beimpossible for any backward movement to occur unless some of the partsbreak, and if the pawl is released before its `full downstroke isaccomplished it will remain in the position to which it has been moved,so that the downstroke may be completed at any time, and thus secure thedelivery of the article and avoid danger of the loss of the moneyinserted and the non-delivery of goods. In order to prevent thedisengagement of the catch 29 from the end of the operating-lever, thelug 17 has a threaded opening for the passage of a screw 40, having alock-nut 41. The end of this screw is disposed immediately above thecatch 29 during all the time the latter is in engagement with theoperating-lever after the movement of the latter has been started, andit will be observed that the outer face of this catch is disposed on acurved line struck from the center of movement of the shaft 1 1 so thatthe screw will at all times be in position to prevent disengagement ofthe operating-lever from the catch should the operating-lever be movedfor only a portion of its stroke. On the release of the operating-leverif the full stroke has been accomplished the pawl will move to theopposite angle and will travel rapidly over the teeth. of the rack 21under stress of the heavy tension-sprinfT 23. The coin deposited in thecup 27 comes into contact with a spring 42 at a point near the limit ofdownward movement of the operating-lever, and the coin will thencebeelevated, or rather will be held from further downward movement, whilethe cup continues its downward movement and effects the discharge of thecoin.

In the coin-chute is placed a magnet 45, which serves to deflect anyparamagnetic disk or slugs which may be inserted in the machine.

Having thus described the invention, what is claimed is- 1. In acoin-controlled vending-machine, the combination with a delivery-slide,of a shaft, means for operatively connecting the slide and shaft, anoperating-lever loosely mounted on the shaft, a bell-crank lever securedto the shaft, a spring-held pawl carried by one arm of the bell-cranklever, a rack for engaging the pawl, the distance between thefulcrum-point of the lever and the point of the pawl when the latter isdisengaged from the rack, being greater than the distance between saidfulcrum-point and the rack-teeth, thereby preventing rearward movementof the pawl in advance of the complete stroke of the bellcrank lever, apivotally mounted coin actuated pawl carried by the shorter arm of thebell-crank lever, the outer face of said pawl being on an arcuate lineapproximately concentric with the axis of the shaft, and an adjustablescrew serving to prevent release movement of the pawl until thecompletion of the delivery operation.
